Rain FSD

It works but I wouldn’t trust it much with mad max mode in the freeway. Hydroplaned a few times with all the lane cutting. 95% tire treads

I’ve used it in the rain and it seemed fine. Auto wipers run more often than I’d normally use, but have not had issues. I don’t think I’ve done any heavy rain driving on the freeway though. Pretty sure mostly surface streets.

>So FSD does not work in rain? Why do you think FSD doesn't work in the rain. It works in heavy rain that I personally find difficult to see in, even at night.

> I don’t think I’ve done any heavy rain driving on the freeway though. I did, a year ago. April 2025, finishing up a long road trip, hit heavy rain at 10pm on a dark freeway. Very hard for me to see. I put it in Chill and it ran along in the right lane like there was no problems at all. And this would have been back on a v13 version. I have had FSD disengage in SEVERE rain, like monsoon wipers cannot keep up rain. But no one could see anything and everyone was just pulling over.

Depending also how the rain is … I already drove during a heavy rain in Belgium (EAP only), and Charlotte (surname of my model Y Juniper) have seen the borders of the lane better than me. But, minutes later I stopped EAP because my tesla became blind too … heavy ++ rain.

FSD definitely works in the rain. I drove to southern CA over 500 miles in a driving rainstorm with 40 mph winds, starting at 4 am in the dark, through patches of fog as the rain subsided, from my garage in Sacramento to the driveway of my hotel in Palm Springs over Christmas week with NO problems. FSD confidently swerved around debris, huge tumbleweeds. The only times I touched the wheel was to change lanes when I disagreed with its decisions on the freeway. On the way back on New Years Day, it swerved out of the way of a car jerking into my lane from a blind spot that neither I nor my spouse in the passenger’s seat even noticed until the event was over, saving us from a nasty accident. FSD has sold me. It may not be autonomous, but as an ADAS it’s world class.

It depends on whether the cameras are blocked by rain droplets. I’ve had FSD fail in light rain and slow traffic when the side cameras can’t “see” due to water droplets covering them. Then when traffic starts moving and the water is carried away FSD engages.

Who turns on mad max when it’s raining

Well mad max would for one

I'd imagine it slows way down to compensate, and cybercabs probably don't exceed 45 much

Where did you read that FSD doesn't work in the rain? I can assure you it does in any rain that's also safe for a human to drive through.

More often than not lately cameras are blocked by rain droplets and I need to take over, or ice and snow. How will cyber cab solve for this…have the user get out and wipe it off?

Read? It’s my real life experience

Mine has been giving me warnings about rain blocking side or back cameras while driving but I just swipe the warnings away and FSD keeps on driving just fine. The only thing I’ve noticed affected by it would be lane changing. It hesitates a bit more when they are blocked. Still works fine though. Does yours actually force you to take over?

Once or twice yeah

I'm wondering how people have experienced FSD with heavy fog? If it's foggy enough for me to be a bit scared and very mindful of visibility, does FSD work like a champ in this situation? NorCal/SoCal foggy winter is where I'm mainly driving.

We just had a rainstorm this last week, I could hardly see in front of me and FSD was handling like a champ.

It doesn't work for me in the rain. The camera can't see with water build up over it.

nope. In Florida, FSD is basically useless in the rain.

I can still see out the window but I get the warning that visibility is reduced for FSD. I think that’s teslas I told you so in case it crashes. Back camera is often complete blocked when I get home and have to back into parking. It’s not protected enough from the water that kicks up back there
